Indialantic, FL 32903 Frost Dates

32903, near Indialantic, FL: the frost window

Zone 10a

Typically, the last spring freeze lands around 01/16, roughly 141 days out. Fall's first freeze usually shows up around 01/13, roughly 365 days after the last spring frost.

Zone 10a (30 to 35°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Indialantic, not a forecast for this year.

Stretching the season past the first frost

Indialantic's growing season runs out in roughly 20 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 01/16 isn't a guarantee

01/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/13 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/30 and only about 1 year in 10 sees frost after that.
